Objectives: To evaluate the safety, efficacy, and diagnostic and therapeutic utility of singleballoon enteroscopy (SBE) in Vietnamese patients. Subjects and methods: A retrospective study was performed at Bach Mai Hospital and Miltary Central Hospital 108. A total of 89 patients (56 males, 33 females) who underwent 91 SBE procedures from 01/2011 - 07/2020 were included. Results: 89 patients with mean age being 49.3 ± 19.3, ranging 6 - 88 years were diagnosed with suspected small bowel bleeding and underwent 91 SBE procedures. Antegrade and retrograde approaches were used in 36.0% and 14.6% of subjects, respectively. The mean insertion depth was 249 ± 94 cm beyond the duodenojejunal flexure by the oral route and 132 ± 74 cm proximal to the ileocecal valve by the per anal approach. The mean duration of the procedure for antegrade and retrograde enteroscopy was 95.31 ± 40.42 min and 51.92 ± 29.69 min, respectively. Pan-enteroscopy was present in 51 cases (57.3%). Diagnostic yields in cases of obscure gastrointestinal bleeding (OGIB) were 64 cases (71.9%). The causes of bleeding on SEB included: Angiodysplasia (n = 8); tumors (n = 11), polyp (n = 03), ulcers (n = 22), Meckel’s diverticulum (n = 2) and erosion (n = 15). The number of patients receiving endoscopic intervention was 18/64 cases (28.1%). No severe complications such as perforation and pneumoperitoneum occurred. Conclusion: SBE is well tolerated and has good diagnostic yield. Therefore, SBE may be a useful diagnostic and therapeutic tool in addition to the double-balloon enteroscopy (DBE) for investigating suspected small bowel disease. * Keywords: Single-balloon enteroscopy; Small gastrointestinal bleeding.
